STRAlGHT-WAY VALVE.

- SPECIFICATION forming part of Letters Patent No. 354,019, dated December '7, 1886.

Application filed July 26, 1886.

To all whom it may concern.-

Be it known that I, EDMUND LUNKEN- HEIMER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton,

State of Ohio, have invented certain new and useful Improvements in Straight-\Vay Valves, of which the following is a specification, reference being had therein to the accompanying drawings.

IO This invention relates to the peculiar form of straight-way valves seen in Letters Patent No. 341,424., granted to me May 4, 1886; and

the first part of thepresent improvements consists in constructing the vibrating carrier in I5 such a manner as to relieve the valve-connection of any strain when the loosely-coupled valve is both opened and closed. To accomplish this result I provide the free end of the carrier with a keeper that grasps the edge of the valve, and yet allows the latter to have a limited play,'in order that it may adjust itself to the seat, which seat is usually integral with the shell. This keeper may consist of a short cylinder or annular rim projecting from the front of the carrier; but I prefer using a pair of segmental flanges or wings, inasmuch as they answer all the purposes of the complete ring, and are much lighter, and occupy less space within the shell or casing, as hereinafter 0 more fully described.

The second part of my present improvements consists in making the free end of this carrier somewhat larger in diameter than the valve proper, in order that steam may be prevented striking directly against the back of said valve, as hereinafter more fully described.

The third part of my present improvements consists in attaching a locking device to the valve stem or spindle, which device can be so set as to hold the valve to any specific adjustment, and. thus prevent it being shifted by the vibrations of the engine or otherwise, as here inafter more fully described.

The fourth part of my present improvements 5 consists in constructing the stut'fing-box in such a manner as to prevent the gland of the same being worked loose by the rocking mo tion of the valve-stem, as hereinafter more fully described.

In the annexed drawings, Figure l is an axial section of my improved valve in its closed Serial No. 209,040. (No model.)

condition. Fig. 2 is a plan of the valve with a pair of pipes screwed into the shell and the locking device engaged with one of said pipes. Fig. 3 is a front elevation of the carrier and its loosely-coupled valve detached from the inclosingshell. Fig. 4 is an enlarged transversesection through the stuffing-box, the gland of the same being omitted. Fig. 5 is a similarly-enlarged axial section of the corn- 6 plete stufling-box. Fig. 6 is an endview showing the locking device engaged with a pipe. Fig. 7 shows three different methods of coupling the valve to the vibrating carrier.

The shell A, pipe ends B B, neck or nozzle 6 O, tubular portion D, seat E, and wedge or inclined projection F, being the same as seen in my old patent previously alluded to, require no further description in this specification.

G is the vibrating carrier, having at one end an eye, 9, to admit the square [L of the valve stem or spindle H, while the free end of said carrier is preferably providedwith apair of flanges or wings, I I, that project toward the seat E, so as to fit over portions of the 7 edge or periphery of the loosely-coupled valve J. This loose coupling may be made in any suitable manner; but in Fig. 1 semispherical cavities are made in the centers of the opposite faces of the carrier and valve to receive a ball, X, which 1s free to revolve within said cavities; but in Fig. 7 the back of the valve is shown as crowning or convex atj. J, in the same illustration, shows a rounded boss or bearing projecting rigidly from the valve and seating in a socket, 'g, of the carrier. T", in said illustration, is a reverse of the last arrangement, said boss or hearing T". being in this case applied to the carrier, and adapted to enter a socket, g, of the valve. Either of these, or any other form of coupling, may be used that will allow the valve to yield and bear snugly against the scat E, although the carrier G may not swing in a plane exactly parallel with said seat. In addition to the 5 wings I I, the free end of said carrier has a beveled shoulder, K, that bears against the wedge F while the valve is closing. Furthermore, it is prelerred to make thefree end of this carrier disk-shaped and somewhat larger in diameter than the valve, as more clearly seen in Fig. 3, in order that this enlarged disk may serve as a shield that prevents the current of steam or water "striking directly against the back of the valve, and thereby cause the latter to wear unevenly. i

The tubular portion D of the shell is chambered out at L to afford a stuffing-box, the inner end of which is closed in part by a collar, M, of the valve spindle or stem H, previously alluded to. The outer portion of this stuffing box L is screw-threaded to receive an ordinary adjustable gland, N, whose inner end bears againstan annular flange, O, of asleeve, P, which latter is traversed by the spindle H, as seen in Figs. 4 and 5. This sleeve must be free to be adjusted longitudinally of the stuffing-box, but must not turn within the same, which turning is guarded against by providing said sleeve with a lug, 0, that traverses a groove, l, in one side of said box. This lug preferably projects from the flange 0, although any other expedient may be employed to pre-. vent the turning of the sleeve.

From this description it is apparent that by properly turning the glandNthe sleeveP will be forced down within the stuffingbox L, thereby compressing the packing between the collar M and annular flange O of said sleeve. It is also evident that the rocking motion of spindle H,incidental to the opening and closing of the valve, will neither tighten .nor loosen the gland N, because the sleeve 1? is locked so that it cannot turn. Consequently the motion of the spindle cannot be transmitted to the packing-gland. The outer end'of thisspindle is screw-threaded at h to receive a nut, R, and a D-shaped washer, S, the latter being seen more clearly in Fig. 6. These devices secure to said spindle a locking-piece, T, having an eye at one end that fits loosely over the spindle H, while the opposite end of said locking-piece is provided with a saddle,

t,- adapted to grasp one side of a pipe, b, that is screwed or coupled to the valve-shell.

U is a wrench or spanner that may be used for manipulating the nut R, and when this wrench is to be fastened to the spindle it can be done by the spring-pin a.

V is a handle rigidly attached to the spindle H, and serving to actuate the vibrating carrier, so as to open or close the valve, as oocasion may require.

v The saddle t is at all times in contact with the pipe I), and the nut R is normally loosened in order that the spindle H may be turned to open the valve J the required distance. After this has been accomplished said nut is tightened, thereby clamping the locking device T immovably between the former and the handle V. Consequently the spindle is now locked to said device T t, and as the latter cannot move it is evident said spindle cannot turn either to the right or left. It will thus be seen that this locking device prevents the valve being either opened or closed by the vibrations of the engine, and by simply detaching the wrench U any tampering with said valve can be guarded against. While the valve is being opened the wing I of the carrier bears against the under edge of theformer, and thuslifts it withoutimposlng any strain on the ball X or other coupling; but in closing the valve the other wing, I, bears down upon the upper edge of the former, and thereby forces it against the seat E,on account of the beveled shoulder K of the carrier coming in contact with the wedge F of the shell. Finally, the dotted circular lines in Fig.3 indicate that the flanges I I may be joined, so as to extend continuously around the periphery of valve J, thus forming a short cylinder or annular rim within which said valve would be confined, and yet be free to adjust itself on the loose coupling thereof; but as such a cylindrical keeper would add to the weight of the device and occupy considerable space Within the shell the segments or wings II are preferred.

I claim as my invention-- 1. The combination,in a straight-way valve, of a Vibrating carrier having a pair of lateral flanges that grasp the edge of a loosely-coupled valve, for the purpose described.
